To a whom it nmy concern.-

Be it known that I, WILI'JAM J. Rsrsotns, a citizen of the UnitedStates, residing at Chicago, in the count of Cook and State of Illinois,have invented certain new and useful Improvements in Dust-Colleot-inShields for Radiators; and I do hereby dee are that the following is s.full, clear, and exact description thereof, reference being had to theacoompanyin drawings, and to the letters of reference mar ed thereon,which form a part of this specification.

This invention relates to improvements in dust-shields forheat-radiators, and has for its object to provide a shield which willpre vent the accumulation of dust upon the adjacent well of the room inwhich the radiator is. located, and thereby prevent said well frombecoming discolored, and to also filter the air so it will be thrownback into the room in ev purified condition. It is a well-known factthat the sir-current created by heat from said radiators causes dust tobe drawn from the floor of the room and carried upwardly insaid warmair-current, which naturally-impinlges upon the wall. A portion of thedust wil be deposited, therefore, upon the wall above and in the reer ofsaid radiator, while the remaining portion will be thrown back into theroom.

It is the purpose of this invention to con-- struet a shield which isrovided between the said shield and the ra later with means for arrestindust andforeign substances with which the air-current is charged, and solocated that said current must pass there through, whereby the air willissue from the radiator into the room in a purified eondition. Thedust-arrestin means will be removablymounted in the s 'eld, so that whenit becomes fully charged with (lost it can he removed and cleansed oranother one substituted therefor.

The invention consists in the matters herein illustrated and described,and it will he more particularly pointed out in the claims ap nded tothis speeifiestion.

n the drawings, Figure lis a perspective View of the upper art of aradiator provided with m impr0ved dust-shield Fl". 2 is the same viewwith the hood or cover thereof removed. Fig. 3 is a oross-seotionel viewof the shield. Fig. 4 is a, detail section taken on line 4 4 of Fig. 3,omitting the screens.

In said drawings, B designates as a whole my improved dust-shield, whichis adapted ioiit over the top of a radiator A and to extend beyond theseine some distance both at the front and at the rear thereof. Betweensaid radiator and the shield is located wsuitable screen I), whirh setsto arrest theldust from the upwardly-direrted sir-current, so thet saidmirrent will pass out in the room in a purified condition. and is hereinshown of a protecting-howl B, a screen-support {3, and the screen D. Thescreen-support consists of two end lieces or plates C" C, whii'h areadapted to lB-VQ detachable engagement with the opposite odds of theradiator. Said end pistes C are suitably secured rigidly together hymeans of a plurality of oonneetingmods which serve as the supports uponwhich the screen Dis mounted. zag relation from front to rear of theshiel end the screen 13 is entwined about the same in the manner shownin Fig. 3, the object of the arrangement herein shown being to pro videthe greatest possible screen area for a 1given space. The screenconsists of any open hrio, such as loosely-woven cotton cloth or othersuitable meterial throu h which the air will resdilj ass and which willact to effectw ally arrest a l forms of foreign matter carried by theattending air-current.

An desired means may be provided for (ls-tee sbly securing the screen tothe supporting-rods (3*. As herein shown, the front Said shield consistsSaid rods 5'." are arranged in 2i and resrmost rods are provided ontheir proximate faces with herbs or points c,wliioh are adept-ed to passthrough the opposite ends or side margins of the screen 1) end tothereby hold the screen taut upon said supports. Said screen andsupporting-arms are removably mounted upon the radiator A, as hereinshown, bymeens of supporting-hooks (P, which are attached to the endplates (1" of the supporting-frame an d which overhang the op osite endloo s of the radiator A. Prefer a two of see hooks will be provided oneao end, as shown in Fig. 3, which act to balance the shield. Said hooksC will be se-- oured'to the end plates (3 by means of rivets or thelike.

As a further and separate improvement the hood B is shown as madeseparable from the screen-support. Said hood consists of a hollow easingwhich covers the screen-support and is attached at its opposite ends tothe end walls B. Said end walls B of the hood, as herein shown, areduplicates of the end plates of the screen-supporting lrmne end I OO-IIO when the hood is in place u )on the radiator said end walls B restparal lel with the end plates as shown in section in the detail view ofFig. 4, whereby said end plates are covered by said walls B. Saidseparable hood is provided for convenience in mounting the screen uponthe SCILEl't-SUPPUItS, it being obvious that if the hood were madeintegral with the plate (J of the screen-support frame it would not beso eas to entwine the screen upon the rods C in t e manner illustratedherein. I do not wish, therefore, to limit myself to the preciseconstruction illustrated in the drawings. Neither do I wish to belimited to the precise arrangement of the screen I) as herein shown,because it will be manifest that such arrangement will .be varied tomeet the requirements of any chanues in the form of the other parts ofthe shiel occasioned by the fancy of the designer or by the necessity ofadapting it to various forms of limit-radiators. As a still further andseparate improvement and as a means of preventing the air from beingdeflected under the forward edge of the hood without first passingthrough the i'ilteringsereen D, I have shown said hood as providedbetween the opposite edges thereof with a slot B,Which may extend, asherein shown, from one end thereof to the other. 'lheiwarm air-currmitcreated by the heat ol the radiator will be directed to and through aidslot [3, as indi ated by the arrows in Fig. Ii, it being the highestpoint ol escape thereof m smd hood,'so that none of the muted air wllltend to become deflected beneath the l'orwnrd edge 1) ol the hood. The

e i l lms hood is herein shown and described as applu-d to a radiator,but it ls obviously applir'nble to other u es as, For example, to ahot-air register. In thus using the hood ils shape should conform, ofcourse, to any peculiarity of construction of the register, and the slotB may be differently arranged or even dispensed with and a plurality ol'hot-nil perforations used as desired.

What I claim as my invention is as lot lows:

I. A shield for a radiator comprising a screen-support adapted to restupon a radiator, a dust-collecting screen secured to said support and ahood removably mounted upon said support and serving as a cover for saidscreen. i

2. A shield for a radiator comprising a screen-support adapted to restupon a radiator, a dust-collecting screen secured to said support, and ahood removably mounted upon said support and serving as a cover for saidscreen, said hood having its front and rear edges extending below saidscreen and having an opening above the latter for the passage of airtherethrough.

3. lur'ombination with a radiator, a shield comprising a screeusupporthaving end plates, longitudinally-extending rods connected to said endplates, at dust-collecting screen mounted on said rods, and a removablehood adapted to cover the screen and its supports.

4. A shield adapted to rest u on a radiator, a dust-collecting screenlocateri tln-rein above the radiator, an elongated opening in the frontface of the shield above the screen, and an upturned flange along thefront margin of the opening.

5. A shield comprising means whereby it may be supported upon or above aradiator, supports for the screen located alternately in dillerenthorizontal planes and an angularlyarranged dust-collecting screenthereon.

ln testimonv that I claim the foregoing as my invention allixmyslgnaturedn presence of two witnesses, this 19th day of April, A. l).
